| * spi/pl022: Devicetree support w/o platform dataRoland Stigge2012-09-251-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even with devicetree support, we needed platform data to provide some data, leading to mixed device tree and platform data. This patch makes it possible to provide all that information via device tree. Now, the data must be provided via platform data _or_ device tree completely. Only in case of DMA where a callback specification is necessary (dma_filter()), platform data is the only option.

| * spi/dt: DT bindings documentation: "num-cs" property for SPI controllersRoland Stigge2012-08-221-0/+3
| | | | | | | | | | | | | | | | | | | | Several SPI controller drivers have defined differently named properties for the number of chip selects. Now adding "num-cs" as a reference name for new bindings.

There's nothing too exciting here, mostly it's simple driver specific stuff: - Add spi: to the modaliases of SPI devices to provide namespacing. - A driver for AD-FMCOMMS1-EBZ. - DT binding for Orion. - Fixes and cleanups for i.MX, PL0022, OMAP and bitbang drivers.
